Guarder Enhanced Ver.6 Polycarbonate Tappet Plate.

"works well and good in my tommy gun, very little give and not had one problem.

"Not sure why the other guy had problem with this. I have once of these from way back when I did a Gaurder FTK for my P90. It's been in there for more than 10 years with no issues. Maybe the sector gear cam or nozzel? It's currently still humming along, no signs of stopping and I have even subjected it to a Tienly 45000 and 25/50C 11.1v. At 40+ rps. We shall see how long THAT lasts, but it was fine at around 35rps in my previous setup.

"STAY AWAY FROM THIS! A while back I tried to replace a broken tappet plate in my P90 with this. Only to find my velocity taken a serious drop after installation. Upon closer inspection side by side with the factory tappet plate. I noticed the triangle part of this tappet plate isn't cut correctly, which resulted in heavy air leakage.

There's also the fact that for some reason they decided to make this out of polycarbonate. Which's hard, but also brittle. Consider the fact that the tappet plate really doesn't take on much compression stress during operation. There's really no benefit what-so-ever from the extra hardness. While extra brittleness adds a very real risk of the tappet plate breaking at the 90 degree sharp bent right below the nozzle slot when reciprocating in high speed. Nylon would've made more sense as the material of choice for this particular part.
